Emergency medical dispatching : protocols, experiences and priorities
Each year, millions of people call the emergency number with a wide variety of symptoms and various levels of illness severity. At its’ core, emergency medical dispatching encompasses the answering of these calls, the assessment of the need for medical assistance, the dispatch of a resource with an appropriate priority level and the provision of instructions assisting the caller. Consequently, emergency medical dispatching is important in ensuring patient safety as well as for ascertaining the best use of limited resources. However, research on different aspects of emergency medical dispatch remains limited. Therefore, this thesis’s overall aim was to provide new knowledge in relation to dispatch protocols and the assessment and prioritization of emergency medical calls. Further, to bring light onto emergency medical dispatchers’ (EMDs) experiences of managing such calls thereby creating an understanding and foundation for further development and strengthening of this first link in the chain of emergency care. The thesis builds upon four studies based on different populations: Study I: a simulation study with the aim to compare the accuracy, in terms of correct dispatch priority, between two dispatch protocols; the Swedish Index and RETTS-A. Expert consensus was used as reference standard. A total of 1,293 calls was included. For priority level, 349 (54%) calls were assessed correctly with Swedish Index and 309 (48%) with RETTS-A (p=0.012). Sensitivity for the highest priority was 82.6% (95% CI: 76.6-87.3) for Swedish Index and 54.0% (95% CI: 44.3-63.4%) for RETTS-A. Overtriage was 37.9% (34.2.-41.7%) in Swedish Index and 28.6% (25.2-32.2) in RETTS-A. The corresponding proportion of undertriage was 6.3% (4.7-8.5) and 23.4% (20,3-26.9) respectively. The results demonstrate that although the Swedish Index had a higher accuracy than RETTS-A, the overall accuracy for both dispatch protocols is low. Study II: a retrospective observational study based on registry data from four Swedish regions in 2015. The aim was to ...
